Using hook-ups?

I have always just dry camped with my 27' Prowler TT. I will going on a trip across several states and on a few occasions staying with hook-ups. What will I need to know about this? I have a hose for water, but what about electricity? At home I charge my batteries by plugging my trailer in with an extension cord. Can I do the same at a campsite with hook-ups?

Thanks in advance for any advice.

Using hook-ups?

Rookieone, welcome to the forum. Check the owner's manual for instructions. If you don't have one, get one. Your TT should have a shore power electric line that plugs into outlet at campsite. For charging your batteries (not sure which ones you are referring too) you can use an outlet from within your TT or one on the exterior of your TT to plug in your charger. Don't forget about your black tank or grey tanks and using them and draining them (before you leave the campsite). There again, check your owner's manual. Make sure your hose is clean and for city water use. Check your plumbing for any leaks before you leave for your trip. If your TT has built in batteries, it probably has a charger built in also and when your hooked up to shore power, it may charge your batteries. you said you use an extension cord to charge your batteries by hooking up to trailer and if so, that should mean you have a converter/charger in the TT. Check it all out before you leave....and good luck.
Using hook-ups?

The campsite that I will be staying in says it has 50 amp service. Will I need any thing different to connect to it compared to when I connect at home? Adaptors? or anything like that?
Using hook-ups?

Your trailer has 30 amp service. There is an adapter from 50 to 30 amp. Most campgrounds that have the 50 amp also have a 30 amp plug in the same box. Check with them to see, the adapter is $20-23.00. If the site has both, you won't need the adapter.

When I had a 30 amp trailer, I had an adapter that allowed me to plug into 50 amps, and one which allowed me to plug into 15 amps. In addition to the 30 feet of cable built into the trailer, I carried 30 feet of 30A extention cord, and 50 feet of 15 amp extention cord. Plus I invested in a gadget which plugs in and tells you if the outlet is wired correctly, and shows the voltage and frequency (and possibly one other value, but I can't remember for sure).

The adapters came from Camping World (good ones, with a plug on one end, socket on the other, and wire between them, are about $15), as did the voltage meter. The 30 amp extention cord came from either Camping World or WalMart. I don't know where the 15 amp extention cord came from, but I do remember it was a challange to find one with big enough wire (10ga? 12ga? Certainly no smaller)

If you can afford it, I suggest investigating a 'Surge Guard'. Keeps any problems in the power source from affecting your trailer.

Being a disciple of 'overkill', I built an adapter for 20 amps, but never had a chance to use it, so I would not recommend following suit.

For water, it is handy to have an assortment of brass connections (45 degree and 90 degree) and one of those 'flexi-fittings' (4" hose inside of a big spring) to allow you to hook up to any water source, without stressing the hose. I carry 4', 10' and 25' of drinking water certified hose which should be able to handle most hookup situation, along with a 50' flat (canvas) hose on a reel as a small/light solution for long water runs. All my drinking water hoses and fittings have caps on both ends to keep the dirt and bugs out.

Make sure you have a pressure restriction valve somewhere in your hookup to keep the pressure in the RV to 40 PSI or less. I hooked up to my house briefly without one, and blew the water pump pressure sensor and the tube supplying water to the toilet...

I carry a 'manifold' with 4 individual valved hose fittings, in case I ever have to share a water source. I hook up 1 of the 4 with my drinking water, and 1 for my 'sewer' hose (with anti-siphon valve). And 25' feet of 'gray' hose for cleaning the black tank (via backfill valve or toilet wand). Also a good spray nozzle for general cleaning, and the special fitting to fill the fresh water tank. Finally, don't forget a package of spare hose washers.

It is a good idea to have a filter in the line. I use the one from Camping World which claims to filter out bacteria for about $35.
